What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Catalog the items you hold dear, associate them with categories and storage places. Keep track of items you lend or borrow, as well as how many are currently in your possession. Conceptualize and hierarchize your storage spaces. *** "Items & Storage is a great tool to keep you and your possessions organized no matter what your living circumstances." - cooliphoneipadapps.com *** "Nice application to help keep track of where you have stored things as well as things borrowed, lent, and that you may be running low on." - appcast.com eStorage allows you to catalog any items you want to: household items, tools, goods, documents, collections, etc. There’s no limit to how many item categories can be entered. Each new item can be given a name, description, value (useful for insurance), picture and quantity (set to 1 by default). The bar code reader featured in the app enables you to easily add its ID to an item, and recover the information related to an item (Iphone 3GS/4/5 and new iPad). The items can be associated with the categories you choose: clothes, computer hardware, files, tools, materials, etc. (you can of course create any category you need). In order to easily keep track of lent or borrowed items, eStorage gives you the opportunity to register the information (person, date) related to such operations. To help you easily retrieve your stored items, eStorage enables you to associate them with a storage location: geographic reference, room, piece of furniture, drawer, suitcase, etc. Storage spaces can be organized into several hierarchical levels, like living room / closet / shelf / box, for example eStorage comes with powerful search engines allowing you to instantly retrieve any item, information about it, its lent/borrowed status and storage space on the one hand, or all the items stored in one place or belonging to the same category on the other hand. For users wishing to accurately monitor their item storage levels, eStorage also enables precise quantity management for each item, including the setting of storage shortage alerts to quickly spot items whose quantity is below the predetermined level. eStorage allows you to export the data (items and storage locations) as a CSV file (which can be imported into most spreadsheet programs) or as PDF files, sent by e-mail. This allows you to view and manipulate the data on your computer. Universal application with full resolution support for iPad. iOS 8 or above.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
